Speccaton of Letters Patent.

Patented Dec. 11, 1906.

Application filed March 26,1906. Serial No. 308,109.

To all whom t may concern.-

Beit known that I, WINFIELD O. GUNCKEL, a citizen of the United States,residing at Terre Haute, in the county of Vigo and State of Indiana,have linvented certain new and useful Improvements in Coal-Separators;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to mechanism for separating coal and othersimilar material into various grades-such as lump coal, nut coal, andpea coal and it consists in the novel construction and combination ofthe parts hereinafter fully described and claimed.

In the drawings, Figure l is a side view of the end portions of theseparator. Fig. 2 is a plan view of the same. plan view showing amodification in the arrangement of the rolls in the separator andshowing one of the said rolls in longitudinal section. Figs. 4 and 5 arerespectively an end view and a longitudinal section of one of the springdistance-rings.

A is the frame of the separator.

B represents the separating-rolls. These rolls are journaled in theframe in a series parallel with each other.

The separator is preferably arranged in an inclined position, althoughshown in a hori- Zontal position in the drawings. The material isdischarged onto one end portion A2 of the separator, which is its upperend. The rollers nearest this end A2 are spaced close together, so thatthere are very narrow openings between them, and the rolls at the otherend portion of the separator are spaced farther apart, so that thematerial may be separated into different grades. Suitable means areprovided for discharging the material onto the upper end portions of theseparator and for receiving the different grades of separated material.These means are of any approved. construction and are not shown in thedrawings.

Each roll B consists of a hollow cylindrical shell mounted on a shaft bor having shaft ends b projecting from it.

The rolls are all revolved continuously in the directions of the arrowsin Fig. I, and they all revolve in the same direction.

C represents sprocket-wheels secured to the shaft ends t at one end ofthe rolls. Every alternate roll is provided with a sprocket-wheel C. Dis a drive-chain which Fig. 3 is also a passes around all thesprocket-Wheels C and causes the rolls connected to them to revolve inthe same direction. E represents guidebars which hold the intermediateportions of the upper bight of the drive-chain in engagement with thesprocket-wheels, so that the chain is prevented. from jumping orslipping. The guides may be single continuous bars, or they may beformed in sections, or any other approved guiding devices, such asuidesheaves, may be used. C represents similar sprocket-wheels securedto the shaft ends of the remaining rolls at the other ends of the rollsfrom the sprocket-wheels C. i

D is a drive-chain which passes over the sprocket-wheels C and drivesthem all in the same direction. The drive-chain D/ is provided with aguide-bar E, the same as the drive-chain D.

The sprocket-wheels are all considerably larger than the rolls whichthey drive, so that ample power is provided, and each sprocketwheeloverlaps the shaft ends of the two adjacent rolls, the said rolls beingspaced near together, so as to be effective in screening or separatingcoal. i

.The shaft on one of the rolls is provided with a driving wheel orpulley F, and G represents driving connections operatively connectingtwo of the rolls, so that all the rolls revolve in the same direction.

In the modil'ication shown in Fig. 3 the rolls are arranged the otherway-about from the positions shown in Fig. 2 and so that the material isdischarged onto the end portions of the rolls. In order to separate thecoal into different grades, the centers of all the rolls are arranged atthe same distance apart, and the rolls are made of different diameter atdifferent parts of their length. Each roll B is provided with a shaft orshaft ends t', secured in any approved manner into a tube g'. Gr is anouter tube or shell at one end portion of the tube g, and h representsspring distance-rings between the two tubes. The spring distance-rings7L are split upon one side, and they are tapered externally. Theinternal end portions of the outer tubes G are preferably slightlytapered also, so that when the spring distance-rings are driven forciblyinto the spaces between the end portions of the tubes they are clampedto both tubes, and the tubes are held concentric with' each other.Rivets or pins 'i are driven through holes in the said tubes and rings,so as to secure them permanently in position.

ICO

Y What I'claim isl. In a separatorfthe combination, with a series ofsmooth cylindrical rolls arranged with narrow screening-spacesbetweenthem,

of drivingwheels secured to the alternate rolls of thesaid series zandat one end of the said rolls, driving-wheels secured to the remainingrolls of the series and at the other ends of the said rolls, iieXibledriving devices passing 'around each series of driving-wheels andarranged with their lower bights clear of the intermediate wh eels ofeach series, means forholiding the upper bights oi' the said drive ing'devices in engagement with all the' driving-wheels, and means forrevolving both series'of driving-wheels in the same direction.

2. In afseparator, the combination7 with a series I of vsmoothvcylindrical rolls :arranged withn'arrow screening-spaces between them,of sprocket-wheels secured tO the alternate rolls f the said series andat one end of the saidrollsjsprocket-wheels secured to the' remainingrolls 'of the series and at the other end `of the said rolls,drive-chains passing around eachV series of sprocket-wheels and arrangedwith their lower bights clear of the in termediatewheels of each series,means for holding the upper bights of the 'said drivechains inengagement with all the sprocketwheels', and means for revolving bothseries of sprocket-wheels in the'same direction.

3. In a separator, the combination,- with two series of smoothcylindrical rolls, the rolls of oneseries being arranged alternately ofthe rolls of the other series, and driving-wheels secured to the rollsof one series and arranged at one end of the said rolls, driving-wheelssecured to the rolls of the other series and ar- `.ranged at the otherend of the said rolls, al1

'driving-wheels, and driving devices which connect two of the said rollsVso that all the rolls are constrained to revolveI in the samedirection.

4. In a separator, the combination, with a supporting-frame, a drivingmechanism; of

a series of sep arator-rolls journaled inthe said frame, and providedwithmain tubes having projecting shaft endssecured to them, outer ftubes of larger diameterthan the said main tubes and arranged overportions of the said main tubes at one end of the said frame, and;

distance-pieces secured between the said main tubes and the endportions-of the said outer f tubes, said outer tubes and the exposedportions of the said inner tubes forming'sepa'iating-spaces of diierentwidth for grading the material.

In testimony whereof I have affixed my signature in the' presence of twowitnesses.
